When scientists announced Webb’s first definitive detection of Neptune’s auroras in March 2025, they revealed another surprise: observations taken in 2023 showed that the planet’s upper atmosphere had cooled by several hundred degrees since Voyager 2 visited in 1989—and scientists still don’t know exactly why.
The first definitive detection of auroras on Neptune came with a quieter discovery concealed in the same infrared…

Physics says a spacecraft with mass can never reach the speed of light: as it accelerates closer to c, the energy required rises without limit, so light speed isn’t merely difficult to reach — for massive objects, it’s physically unattainable.
A powerful enough engine can make a spacecraft move faster and faster. That familiar sentence contains a trap:…
In 1997, scientists sent cameras down with sperm whales to find the monster hidden in their scars: the giant squid. The footage they wanted never came, but the failed hunt helped point science toward one of the deep ocean’s most elusive animals
Sperm whales come up from the deep wearing evidence. Rings of pale scar tissue across the head and…
